United States Patent 3,087,669 PAPERBQARD SHOPPING BAG Felix A. Russell, Colorado Bldg, Lincolnia, Va. Filed Dec. 8, 1960, Ser. No. 74,650 Claims. (Cl. 229-54) The present invention relates to a paperboard shopping bag and it consists in the combinations, constructions and arrangements of parts herein described and claimed.

Generally there is provided a collapsible paperboard shopping bag which in one form of the invention is composed of a single blank of material which may be folded and thereafter joined along two of its edge portions to provide a shopping bag of approximately hip height and which, when in collapsed condition is substantially flat so that a great many of such devices may be shipped in a minimum of space. When the device is opened it may be drawn along a floor or the like by means of a convenient hand opening. In this form of the invention, the two edge portions which must be interconnected may be so interconnected by means of staples or the like. One of the panels of the device is integrally extended downwardly and is provided with integrally formed skid members which are adapted to engage the floor or the like when the bag and its contents are moved from place to place about a store, for example, by a shopper. In another form of the invention, there is provided a relatively stiff panel provided with downwardly extending integrally formed skids to which three sides of a conventional bag structure may be aflixed by stapling, gluing or the like. In this form of the invention also, it will be apparent that the device may be shipped in substantially fiat condition when the same is collapsed. The devices are such that they lend themselves to very inexpensive manufacture and may be utilized by stores, particularly in shopping centers in such manner that they may be sold in direct competition with the conventional shopping bag at very little increase, if any, over the price of such shopping bag. One of the novel features of the invention is the provision of novel skid members which may, if desired, be impregnated or coated with any suitable substance, such as polyethylene or the like for increasing the rigidity and wear resistance thereof.

It is accordingly an object of the invention to provide a novel paperboard shipping bag of the character set forth which is simple in construction, inexpensive to manufacture and yet effective and eflicient in use.

Another object of the invention is to provide, in a device of the character set forth, novel ground-engaging skid members forming a part of the invention.

A further object of the invention is to provide, in a device of the character set forth, novel means for formulating the same from a single blank of paperboard material.

Still another object of the invention is to provide a device of the character set forth wherein portions of a conventional paper bag and a substantially rigid paperboard panel are utilized in the construction thereof.

A still further object of the invention is to provide a device of the character set forth which lends itself to display advertising which may be carried conveniently thereon.

Other and further objects of the invention will become apparent from a reading of the following specification taken in conjunction with the drawings, in which:

FIGURE 5 is a further enlarged fragmentary perspective view illustrating certain skid members forming part of the invention,

FIGURE 6 is a plan view of the single die cut paperboard blank used to fabricate the bag of FIGURES 1 through 5, inclusive,

FIGURE 7 is a perspective view of a modified form of the invention,

FIGURE 8 is a plan view of the device shown in FIGURE 7,

FIGURE 9 is a side elevational view of the bag shown in FIGURE 7, and

FIGURE 10 is an enlarged side elevational view, partly broken away, of the bag shown in FIGURE 7, illustrating the same in collapsed condition.

With reference now to FIGURES 1 through 6 of the drawings, the numeral 11 designates the shopping bag as a finished article, while the numeral 12 generally designates the die cut paperboard blank from which shopping 'bag 11 is formed. Bag 11 (and blank 12) comprise front and rear rectangular panels 13 and 14, respectively. Panels 13 and 14 are joined by a pair of V-shaped side panels 15 and 16 defined by scored fold lines .17 and 18 forming hinge-type connections thereof to the panels 13 and 14, and by a medial fold line hinging the panels 15 and 16 for inward folding thereof in the collapsed condition of the bag 11 shown in full lines in FIGURE 3.

Blank 12 has a second pair of V-shaped panels 20 and 21 of the same size and shape as panels 15 and 16. Panel 21 is hingedly connected to the left margin of front panel 13 by the scored fold line 22. The panels 20 and 21 are articulated along the fold line 23 corresponding to fold line 19. The free edge of panel 20 carries the integral attachment strip 24, their hinge-forming joint being the scored line 25. In the finished shopping bag, the attachment strip 24 is stapled or otherwise fastened (as by the use of adhesive materials) to the free edge of the rear panel 14, as best shown in FIGURE 1, the staples being designated 26. The bottom of the bag 11 is closed by another row of staples 27, or equivalent fastening means.

The lower edge of panel 13 is provided with a serrated extension providing spaced skid fingers 28. However, for greater strength, the lower edge of panel 14 may be formed with mating fingers (not shown). Fingers 28 and the adjacent bag portions are desirably impregnated or coated (at 29 in FIGURES 4 and 5) with any suitable substance, such as polyethylene, for increasing the toughness and wear resistance of the skid portion of the bag. The comb-like skid portion formed by the fingers 28 minimizes friction and prevents the collection of any dust along the leading edge of said skid portion.

The panel 13 is conveniently provided with a handle by simply die cutting a horizontal hand-receiving slot 30 parallel to and adjacent the upper edge of panel 13, as shown.

In the species of FIGURES 7 through 10 the base panel 31 only is shown as being made of relatively stiff paperboard. Said paperboard may be of corrugated or other anulti-ply construction, as desired. The rear panel 32, the medially creased side panels 33 and 34, and the inwardly folded, overlapped and pasted bottom panels (conventional construction and collectively designated at 35) are formed from a single blank of kraft or like paper of desired weight, strength, moisture-resistance, etc.

The front edges of the side panels 33 and 34 have integral strip extensions 33s and 34s for being cemented or otherwise fixed to the margins of the 31, as best shown in FIGURE 7.

Base panel 31 also has its lower edge serrated to provide skid-type fingers 36. Fingers 36, like fingers 28, are also preferably coated and/ or impregnated with polyethylene or other suitable substances to improve their toughness, rigidity, wear resistance and/or low-friction surfacing. A finger receiving slot 37 may be employed to provide an inexpensive and effective handle, as in the first described species.

It will be apparent that, instead of the skid fingers 28 or 36, the lower edge of the panel 13 or the panel 31 may itself extend downwardly a sufficient distance to become ground-engaging. In this instance (not shown), it would again be preferred that the ground-engaging portion of such panel be impregnated or coated with a stiffening and wear-resistant material.

While but two forms of the invention have been shown and described herein, it will be readily apparent to those skilled in the art that many minor modifications may be made without departing from the spirit of the invention or the scope of the appended claims.
